TransactionResult type differs from protobuf schema

[illia-malachyn]

This is part of #736

TransactionResult type on the SDK side
https://github.com/onflow/flow-go-sdk/blob/master/transaction.go#L620

TransactionResultResponse message in the Protobuf schema
https://github.com/onflow/flow/blob/master/protobuf/flow/access/access.proto#L416

computation_usage field is missing

vs

flow-go-sdk/transaction.go

Lines 620 to 628 in 2689460

	type TransactionResult struct {
	Status TransactionStatus
	Error error
	Events []Event
	BlockID Identifier
	BlockHeight uint64
	TransactionID Identifier
	CollectionID Identifier
	}

The main difference is the SDK is missing these fields: metadata, computation_usage.

Let's go ahead and add them.

status_code can be ignored.
